Role of a heterotrimeric G protein in regulation of Arabidopsis seed germination.

Plant physiology - 1 Jun 2002

Ullah Hemayet, Chen Jin-Gui, Wang Shucai, Jones Alan M

Abstract excerpt

Seed germination is regulated by many signals. We investigated the possible involvement of a heterotrimeric G protein complex in this signal regulation. Seeds that carry a protein null mutation in the gene encoding the alpha subunit of the G protein in Arabidopsis (GPA1) are 100-fold less responsive to gibberellic acid (GA), have increased sensitivity to high levels of Glc, and have a near-wild-type germination...
